Fast isn't a the selling point for me either. I get in and out of my current 5+ year old bindings as conveniently as anyone. I'm on the fence about the toe strap vs toe cap feature. The latter isn't available on Flows due to the uni-strap design to aid the entry position as far as I can tell. I don't have any problems without the toe cap now, but was thinking it would provide a slightly better lock-in.
I love me some toe caps.
